The Glasgow Warriors will have branding rights for the 10,887 capacity, all-seated stadium in Glasgow's West End. The deal also enables the Warriors to run and manage all their events at the stadium directly, including match operations and hospitality.
Glasgow Warriors captain, Alastair Kellock, said: "Firhill is a great facility and the deal is much like the one that The Ospreys have at Liberty Stadium, which I think was a huge factor in helping them win the league.
"We have some good, fast runners in our squad for next season so the surface will be a major benefit to us as well as the fact that we will be playing in Glasgow."
